St. John Eudes (17th century): “For how is it possible that Christians should fall into such disorders, or lead such scandalous lives as so many do, if they only bore in mind that they had made a contract with God, in which they had promised never to enter into sin, and to maintain inviolable fidelity to the Divine Majesty; if they only thought that in violating this promise they should lose the grace which God had given them in Baptism, and forfeit the right which they had acquired to the inheritance of eternal life, and become again the children and slaves of Satan.”
